Compare Focal Bathys MG Wireless Headphones vs Sennheiser HDB 630 Wireless Over-Ear Headphones

ANC is good to very good and clearly improved over the original, but the consensus is that Sony and Bose still cancel more noise overall, especially in the mids. The three-mode ANC system gives useful control with Silent, Soft, and Transparency options, even though there is no true ANC-off mode.

ANC performance is generally rated good to very good, especially for low-frequency rumble, but usually a step behind the strongest Sony/Bose/Apple implementations. A minority of takes place it closer to the leaders, while others call it only average for the price. ANC is highly adjustable through the app, with adaptive and manual control plus optional wind-related processing, making it easy to tune for different environments.

Android support is straightforward, with repeated references to Android compatibility in specs, pairing, and app support.

The Focal & Naim app is useful for basics like ANC, EQ, personalization, lighting, and battery view, but several reviewers find it limited or occasionally glitchy.

The Smart Control Plus app is repeatedly called a standout, bundling EQ, ANC, connection management, firmware updates, and extras like sound zones and find features. A few reviewers mention occasional glitches, especially when the dongle is connected.

aptX support is a clear plus and is repeatedly listed as part of the headphone's strong everyday wireless feature set.

aptX family support is frequently cited as a major advantage, and the included dongle helps enable higher-quality aptX links on devices that otherwise lack them.

Latency varies by device and mode. With the dongle, it is often good for movies and casual gaming, but several reviews note it is not truly esports-grade and real-world results may sit closer to typical Bluetooth latency.

Bass is generally praised for depth, slam, texture, and control, though several reviewers note the default tuning can run a little warm, boomy, or heavy before EQ.

Bass is typically tight and controlled rather than boosted. Some call it punchy and physical, while others describe sub-bass quantity as lean; bass boost and EQ can add weight, but pushing hard can thicken or muddy the presentation.

Battery life is solid rather than class-leading, with the commonly cited 30-hour Bluetooth figure generally holding up well in real use. Battery replacement appears possible through Focal service rather than as a user-swappable design, offering some serviceability without true end-user replaceability.

Battery life is consistently excellent: many quote around 60 hours with ANC, and measured tests still land in the low-to-mid 50s. Hi-res modes and dongle use can reduce runtime but remain strong for the class.

Bluetooth performance is usually stable with fast pairing and dependable everyday use, but a few reports mention quirks rather than flawless behavior.

Bluetooth connectivity is mostly stable once paired, with occasional quirks around device switching and initial dongle pairing on some setups.

Build quality is one of the strongest consensus positives, with premium materials, excellent finishing, and solid construction throughout.

Build quality is generally solid, but multiple reviews note that materials feel more plastic than premium for the price, and a few mention creaks or rattle.

The built-in DAC and hi-res USB playback are among the headphone's clearest differentiators, and many reviewers treat DAC mode as a headline feature.

Physical controls are a strength, with tactile buttons and switches that are generally easier to trust than touch panels.

Physical controls are minimal and straightforward, with most interaction handled by touch. Some reviewers wish the lone button were mapped to a different shortcut.

The included cables are generally described as acceptable to durable, even if they are not luxurious extras.

Included cables are generally considered useful and of decent length and quality, though a few nitpick terminations or the lack of inline mic support on analog.

The carry case is repeatedly praised as protective, slim, and premium, even if a few users still find it bulky in a bag.

The carry case is widely praised as sturdy and well-organized with pockets for cables and the dongle; size is the primary drawback.

Fast charging is a practical plus, with the widely repeated 15-minute top-up for roughly five hours of playback.

Charging is frequently praised for speed, with several reviews citing around 7 hours of playback from a 10-minute top-up and roughly 1.5-2 hours for a full charge.

Clamp is generally better judged than on the original Bathys, feeling secure without being overly oppressive for most listeners.

Clamping force is usually described as moderate and improved versus Momentum 4, helping stability without feeling overly tight. Fit-dependent seal changes can still affect comfort and tonality.

Codec support is serviceable rather than cutting-edge: aptX and aptX Adaptive are welcome, but multiple reviews call out the lack of broader premium codec coverage.

Codec and input support are broad: Bluetooth 5.2 with modern aptX options plus wired USB-C and analog. Not every premium codec is supported everywhere, but overall flexibility is a key selling point.

Long-session comfort is one of the Bathys MG's most consistent wins, with many reviewers praising fatigue-free wear over flights, workdays, or extended listening.

Long-session comfort is generally strong thanks to thick padding and moderate clamp, but people with larger ears, heat sensitivity, or shallow-pad discomfort may fatigue sooner.

Design is a major selling point, with the chestnut finish, leather, metal accents, and illuminated logo giving the Bathys MG a clearly luxurious identity.

Design is understated and professional with matte black and subtle accents. Some appreciate the minimalist look, while others find it plain or less premium-looking than similarly priced rivals.

The included 3.5mm and USB-C wired options add real convenience for travel, desk use, and higher-quality listening beyond Bluetooth.

The BTD 700 dongle is valued for enabling better codecs (especially for iOS), improving perceived resolution, and offering lower-latency modes. Setup can be finicky, the protruding plug raises durability concerns for some, and calls or app behavior may worsen in dongle mode on certain devices.

Softer, more supple pads are a meaningful upgrade, improving comfort, seal, and overall premium feel.

Earpads are frequently described as thick, soft, and good at sealing for isolation. The tradeoff is increased heat retention during longer sessions.

The cups offer enough articulation to sit comfortably and fold flat, but the headphone is not especially compact and does not fold into a tighter travel shape.

Swivel range helps the cups lay flat for storage, but one reviewer notes the rotation can be so free that small asymmetries in fit may affect tonal balance.

EQ is helpful and usable, but the five-band structure is repeatedly described as limited compared with fuller parametric options.

Equalizer tools are a highlight: a five-band parametric EQ with A/B bypass enables precise tuning that can meaningfully tailor bass and treble without third-party apps.

Reviewers consistently describe the tonal balance as natural, balanced, or close to reference in the better presets, with cleaner frequency relationships than the original Bathys.

Several reviewers highlight target-curve or reference-leaning balance and good tonal accuracy. Fit and seal still matter, with small positioning changes affecting bass and lower-mid response.

The headband and slider system is easy to adjust and feels premium, helping users dial in fit without fuss.

Headband adjustability is typically smooth and offers enough range to dial in fit, contributing to stable wear.

The yokes and hinge-related hardware are widely described as sturdy, well finished, and built to last.

The included bundle is straightforward but useful, typically covering the hard case plus 3.5mm and USB-C cables.

Included accessories are unusually generous for the category: the dongle, multiple cables, adapters, and a robust case are common value-add callouts.

Instrument separation is frequently singled out as excellent, with strong channel separation, precise placement, and the ability to keep dense mixes organized.

Instrument separation and layering are recurring strengths, helping dense mixes stay intelligible and improving localization, especially with higher-quality sources.

The built-in mic setup is a practical part of the package, handling calls, assistants, and ANC duties without standing out as a weak point.

LDAC is a notable omission and one of the most commonly cited feature complaints at this price.

At louder playback levels the Bathys MG generally stays composed and detailed, but some reviewers still hear treble edge on bright material, so max-volume behavior is good rather than perfect.

At higher listening levels, most impressions suggest the sound stays composed and low in audible distortion. A major caveat is that hands-free call modes on some platforms can drop audio bandwidth and make music sound noticeably worse.

The microphone array does a respectable job suppressing background noise and keeping speech intelligible, though wind and harsher noise are not fully erased.

Noise reduction for calls is generally competent, keeping speech intelligible in moderate noise. Very loud environments and mode changes can still reduce clarity.

Call quality is generally solid, with voices coming through clearly and naturally even if the very best Sony-style call performance is still a step ahead.

On standard Bluetooth, most reviewers report clear voice pickup suitable for work calls. Using the dongle or triggering hands-free profiles on certain platforms can degrade call audio or music quality, so results depend heavily on device and mode.

Midrange performance is a major strength, delivering clear, rich, weighty instruments and improved vocal/instrument resolution over the original, even if a few reviewers wanted vocals pushed further forward.

Midrange performance is consistently praised for clean, realistic vocals and strong detail retrieval. A couple reviewers note a bit of forwardness around 1-2 kHz that can sound slightly shouty depending on fit and seal.

The Bathys MG works broadly across phones, computers, tablets, and wired sources, making it easy to use across mixed-device setups.

Multi-platform use is a core strength thanks to Bluetooth plus USB-C and analog options, with the dongle helping iOS users access higher-quality codecs.

Multipoint is supported and often works well, though several reviewers mention occasional switching quirks that keep it from feeling completely polished.

Multipoint use (two devices) is supported and often works well, but there are limitations when mixing the dongle with other connections and occasional reports of source confusion.

Passive isolation benefits from the over-ear seal and softer pads, though seal sensitivity with glasses is noted by at least one reviewer and total isolation still leans on ANC.

Passive isolation is above average thanks to thicker pads and a strong seal, helping even before ANC is engaged.

Portability is decent for a premium over-ear: the headphone folds flat and the revised case is slimmer, but it still is not a truly compact travel design.

Portability is mixed: cups lay flat but the headphone does not fold inward, so it takes more space than some travel rivals. The case is protective yet can be bulky.

Preset profiles, especially Dynamic, are viewed positively and can materially improve tonal balance depending on listener taste.

Preset EQ profiles and quick toggles like bass boost are generally effective and easy to use. Power users still prefer the parametric EQ for more surgical control.

Replaceable earpads are explicitly mentioned and add welcome long-term serviceability.

Convenience sensors are sparse, with at least one reviewer specifically calling out the lack of wear detection.

Wear sensors add convenience (auto play/pause, auto-on), but sensitivity can cause accidental wake-ups for some; most note these features can be disabled.

Sidetone adjustment is present in the app, but it is not explored deeply enough in reviews to suggest anything beyond basic usefulness.

Smudge handling is mixed: matte cups are often described as fingerprint-resistant, but some materials (notably the headband on some units) can pick up grease and grime easily.

Setup is usually straightforward, but the app and feature set are not always as polished or flexible as the best consumer-audio ecosystems.

Setup is usually straightforward, but dongle pairing steps and occasional app quirks can add friction. Some advanced features require extra steps (like enabling specific audio modes) depending on device.

Across the file, the Bathys MG is repeatedly described as one of the best-sounding wireless headphones available, with standout refinement, detail, dynamics, and realism. Wired listening is a real strength, especially in USB-DAC mode, with reviewers repeatedly hearing cleaner, higher-resolution playback than over standard Bluetooth.

Across reviews, sound quality is the headline: balanced, highly detailed, audiophile-leaning tuning that competes with top wireless flagships and scales up with the dongle or USB-C. A few reviewers find it less instantly exciting than bass-boosted rivals, but overall fidelity is widely praised. Wired playback (especially via USB-C) is often cited as the cleanest, most resolving path. Analog input works too, but the headphone typically still relies on internal DSP and battery power.

For a closed-back wireless design, the Bathys MG earns unusually strong soundstage marks, with convincing width, layering, and better spatial openness than most ANC rivals.

Soundstage is considered roomy for a closed-back wireless, with better depth and separation than Momentum 4; crossfeed and the dongle can change the sense of space. It still cannot match open-backs, and a few listeners describe it as more in-head than speaker-like.

Spatial audio is absent, and several reviewers explicitly note that Focal prioritized core sound over that feature.

Spatial audio as a dedicated virtualized mode is often noted as absent; instead, Sennheiser emphasizes EQ and crossfeed-style processing for older mixes.

Fit stability is mostly good for seated use and commuting, but a few comments suggest movement-related thumping or shifting during more active use.

The packaging and material story show some environmental consideration, including recycled or FSC-style materials in the box and presentation.

There are no touch controls here, so anyone wanting swipe gestures or tap controls will not find them.

Touch controls are feature-rich, but experiences vary widely: some find them refined and responsive, while others report misreads or frustration with pinch-based ANC gestures.

Transparency mode is considered effective and natural enough for conversations and situational awareness without removing the headphones.

Transparency mode is typically described as usable and convenient, with adjustable levels and quick toggles. It is rarely considered best-in-class for naturalness, and some reviewers rate it merely adequate.

Treble is mostly clear, smooth, and detailed, but a few reviewers hear some edge or heat up top, especially on bright recordings or at louder levels.

Treble is often described as detailed and generally well-controlled. Opinions diverge: some hear extra energy up top or a dip in the mid-treble that can make the presentation feel a touch closed-in, and sensitivity varies by listener and fit.

USB-C is central to the product experience, handling charging and the high-value DAC mode for higher-resolution wired playback.

USB-C is a versatility highlight for both charging and wired digital audio, and is frequently cited as the cleanest connection option.

Voice assistant access is built in and works as expected through the dedicated button and supported platforms.

Voice assistant integration is supported and typically works as expected via a dedicated button or gesture.

Volume output offers solid headroom and gets loud enough to help overcome moderate ambient noise. Heavy EQ boosts can reduce available peak volume due to protective preamp behavior in the app.

No official water or sweat rating is typically noted, so these are better treated as commute and travel headphones rather than workout gear.

At about 350g the Bathys MG is not especially light, but most reviewers still find the weight well managed and comfortable in practice.

At roughly 311g, weight is noticeable but often well-distributed. Some still prefer lighter competitors for all-day travel comfort.

Xbox support is commonly described as limited, with at least one review noting the dongle route does not work on Xbox.
